وَبِهَذَا الْإِسْنَادِ عَنْ مُحَمَّدِ بْنِ يَعْقُوبَ عَنْ عَلِيِّ بْنِ مُحَمَّدٍ عَنْ سَهْلِ بْنِ زِيَادٍ وَمُحَمَّدِ بْنِ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ أَبِي نَصْرٍ عَنْ مُحَمَّدِ بْنِ عُبَيْدِ اللَّهِ قَالَ: سَأَلْتُ الرِّضَا عَلَيْهِ السَّلَامُ عَنْ غُسْلِ يَوْمِ الْجُمُعَةِ فَقَالَ: وَاجِبٌ عَلَى كُلِّ ذَكَرٍ وَأُنْثَى مِنْ عَبْدٍ أَوْ حُرٍّ.
Muhammad ibn Ya'qub, from Ali ibn Muhammad, from Sahl ibn Ziyad, and Muhammad ibn Yahya, from Ahmad ibn Muhammad, from Ibn Abi Nasr, from Muhammad ibn Ubaydullah, who said:
I asked Al-Ridha عليه السلام, about the ritual bath on Friday. Imam عليه السلام said: It is obligatory upon every male and female, whether slave or free.
